submodule update doesn't work with relative submodule paths (in GitPython 2.1.14)

[Genovese-martijn]

When using the git.objects.submodules.base.Submodule.update method (https://gitpython.readthedocs.io/en/stable/reference.html#git.objects.submodule.base.Submodule.update), the git python module seems to fake a git submodule call with git clone. It executes git clone -n --separate-git-dir=<workspace>/.git/modules/<submodule_path> -v <submodule_url> <workspace>/<submodule_path>. This command doesn't work when a submodule is specified as a relative path in the .gitmodules path. For example:

[submodule "main_project/submodule"]
  path = main_project/submodule
  url = ../../other_project/some_module.git

The git.objects.submodules.base.Submodule.update then fails with `repository '../../other_project/some_module.git' does not exist.

The regular git submodule command is able to resolve the paths.

Thanks for posting. Which version of GitPython are you using?

Even though the submodule implementation may not be up to date with what git produces, I remember that some improvements were made in the past which might resolve this issue.

[Genovese-martijn]

Thanks for the feedback, I am using version 2.1.14 due to external python2 requirement. The issue is indeed resolved when using version 3.0.3.

Thanks for your reply! I am closing this issue as it is already resolved.

Interestingly, in the last released version of GitPython with Python 2 compatibility, the submodule improvements should already be present. If you can spot the difference, I would be happy to receive a PR against 2.1.14 that fixes the issue there as well and release 2.1.15.

Sorry, I made a mistake in my setup while I was testing it with python3 and git python version 3.0.3. On version 3.0.3 the relative submodule paths also does not work

This bug is still present in 3.0.5 any chance to increase priority?

[Byron]

I am afraid there is no priority beyond what people decide to contribute. GitPython is in maintenance mode.
